LG Twins and Doosan Bears, who share Jamsil Baseball Stadium as their home, have a unique tradition after their head-to-head matches. When moving to their respective locker rooms, the winning team crosses the field, while the losing team moves through a narrow corridor inside the stadium. This unwritten rule, established in 2013, aims to avoid awkward encounters in the uncomfortable aftermath of a fierce competition.
The Doosan locker rooms are located on the first-base side, while the LG locker rooms are on the third-base side. Therefore, this locker room movement applies only when LG is the home team and uses the first-base dugout. If LG wins, they cross the field from the first-base dugout toward the third-base side; if Doosan wins, they cross in the opposite direction. When Doosan is the home team, both teams use the passages behind their respective dugouts.
During the Jamsil rivalry series held last weekend (19th–21st), LG was the home team. In the game on the 21st, LG hit five home runs and won 9-3, sweeping the three-game series. LG players then walked from the first-base dugout across the field to the third-base locker room for three consecutive days.
This marks the first time since the 3rd–5, 2009, that LG has won all three home games in a Jamsil rivalry series. Although LG has achieved sweeps in the interim, coincidentally, all those victories occurred during Doosan home games.

This victory holds special significance for LG because the three-game series last weekend was the final home series against Doosan in Jamsil Stadium history. Starting next year, both teams will play at a temporary baseball field within Jamsil Stadium for five years, and from 2032, they will move to a newly constructed dome stadium as their home. During this three-game series, LG also held a 'Classic Day in Jamsil' event, during which both teams wore vintage uniforms.
In this season's matchups, Doosan was assigned nine home games, while LG was assigned seven. Following the series from the 5th–7, LG concluded its three-game home series against Doosan with this match. One remaining game will be scheduled later as a make-up game. The two remaining three-game series (July 31–August 2 and the 1st–3) will both be Doosan home games. Henceforth, the sight of both LG and Doosan players crossing the Jamsil Stadium field for three consecutive days will remain a memory that will never be seen again.

The history of the Jamsil rivalry has always mirrored the rise and fall of both teams. From 2016 to last year, over a 10-year period, the final season standings and head-to-head results between the two teams were always identical.
From the mid-2010s, when Doosan made the Korean Series for seven consecutive years, until 2021, Doosan held the upper hand in head-to-head records against LG for six consecutive seasons. Notably, in 2018, Doosan lost only in the final matchup of the season, posting an overwhelming record of 15 wins and 1 loss.
However, as LG emerged as a powerhouse, winning championships in 2023 and 2025, it has dominated Doosan in head-to-head matchups for four consecutive seasons up to last year. This season, LG currently leads with a record of 7 wins and 2 losses.
In the final game of the three-game series against Doosan on the 21st, LG hit four home runs in the first inning—the first time in KBO League history for a single inning—by Song Chan-ui, Austin Park Dong-won, and Moon Jung-bin. The team also reached a milestone of 4,000 career home runs in franchise history, achieved by Moon Jung-bin in the bottom of the fifth inning. Perhaps these powerful hits were a celebration of achieving a 'fitting finale' in the final home three-game series against the Jamsil rival.
